Can't search for prefixes by community: Community malformed: AA:NN
Closed, ResolvedPublicBUG


I'm unable to search for prefixes with a particular community, this results in: Community malformed: AA:NN

For example:

vyos@r1:~$ show ipv6 bgp community 60927:666
% Community malformed: AA:NN

I also tried this directly using FRR but there I get the same issue:

root@r1:~# vtysh -c 'show bgp community 60927:666'
% Community malformed: AA:NN

As a workaround a made a community-list and filtered on that instead.
